SLElGH-KNEE.

SPECIFICATION forming part of Letters Patent No. 257,651, dated May 9,1882. Application filed January 20, 1882. (No inodel.)

To all whom it may concern:

Be it known that I, BENJAMIN F. BROWN, of Houghton, in the county ofHoughton and State of Michigan, have invented a. new and usefulImprovemeutin Sleigl1-Knees, of which the following is a full,clear, andexact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

. ing of the same.

The invention consists in asleigh-knce made with a horizontallyprojecting flange around its upper part near its upper end, anddownwardly-projecting flanges upon the sides of its lower end, andhaving holes to receive the fastening-bolts and recesses and holes toreceive the strengthening-pins; also,in the combine. tion, with therunner and the beam, of a knee having a horizontally-proj ectin g flangearound its upper part, and downwardly projecting flanges at the sides ofits lower end bolts for fastening the knee to the beam, and pins forstrengthening the connection between the rugner and beam, whereby astrong, durable, and firm connection is formed between the said runnerand beam; and, also, in the projection rising above the top flange toenter the beam,

whereby the fastening-bolts are relieved from g the strain, as will behereinafterfully described.

A represents the runner, B the beam, and G the rave, of a sleigh. D isthe knee, which is cast of malleable iron.

The kneeD is made hollow, and with a horizontally-projectin g flange, E,around its upper part at a little distance from its upper end,theprojecting upper end, D, being designed to enter a recess in the lowerside of the beam B to relieve the fastening-bolts from the strain.

The lower end of the knee D rests upon the runner A or upon a plate, F,placed upon the upper side of the said runner A, is flared in front andrear, and has downwardly-projecting flanges G uponits side edges tooverlap the sides of the runner A or plate F.

In the flange at the sides of the upper end of the knee D are formedholes H, to receive the bolts I, which pass through them and throughholes in the beam B.

In the front and rear edges of the flange E are formed recesses J, andin the projecting parts of the lower end of the knee D are formed [holesK, to receive the strengthening-pins L,

which pass through them,'through holes in the beam B and rave G, andinto holes in the runner A, as shown in Fig. 1.

- The rave 0 isbent downward in front and rear of the beam B, and itsends are secured to the upper side of the runner A.

With this construction the knee will be strong and durable, and willform a firm connection between the beam and runner.

With this construction, also, should the knee be broken, it can bereadily replaced with a new one without its being necessary to take thesleigh to a mechanic.

Having thus described my invention, I claim as new and desire to secureby Letters Patent vided with the horizontal flange E around its upperpart, a little below its upper end, D, having perforations H in itssides to receive the fastening-bolts and recesses J in its front andrear to receive the strengthening-pins, and having its lower end flaredat the front and rear and provided with perforations K and flanges,substantially as set forth.

2. The combination, with the runners A,--'the beam B, having its lowerside recessed, and the brace O, perforated and having its epdssecured tothe runners, of the knee D, provided with the perforated and recessedflange E around its upper part, a little below the upper end, D, anddownwardly-projecting flanges G on the sides of its flaring lower part,the fastening-bolts I, and the strengthening-pins J, substantially asand for the purpose set forth.

BENJAMIN FRANKLIN BROWN.
